Keep your Blah brain warm when you remember to take it out with you in colder conditions. Then when you come home and leave it in its jar, it won't be in a mood with you and you can discuss the hilarious events of the day such as when Old Man O'Connor slipped on the ice and fell off the Dam and landed on his neck. Good times. Sit among friends in perfect harmony around a heating unit in a pub garden drinking real ale with a warm brain. Relax at home around a nice hot fire with biscuits and tea. Play Chess. Smoke a pipe. Pat the dog on its stupid little head. Re-mortgage the house. Book a holiday to Majorca. Buy a beanie. You deserve it.
